Re-named in 1845 by Wilhelm Karl von Haidinger because of the common tetrahedral form of its crystals. Originally called argentum rude album by Georgius Agricola (Georg Bauer) in 1546 because it contained silver, although it may not have necessarily been silver-dominant as a related mineral, freibergite, is. Named Fahlerts and other names by Johan Gottschalk Wallerius in 1747, while in 1758, Axel Cronstedt used the spelling fahlerz and also used a multi-word chemical descriptive for the mineral. Fahlerts/fahlertz is derived from German fahl = ash-colored and ertz = ore in allusion to its grayish black color.
